WILLIAM L. MERSFELDER, OF KENNEDY HEIGHTS, OHIO.

GAS-OVEN.

Application filed July 8, 1916.

To all whom it may concern:

Be it known that I, IVILLIAM L. MERSFEL- DER, a citizen of the United States, and a resident of Kennedy Heights, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gas-Ovens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to gas ovens for stoves and has as its object the providing of a draining means which will prevent the condensation water resulting from the introduction of heated air into the cold oven, from running out onto the floor.

My invention particularly relates to doors in use with gas attachments for combination gas and coal stoves. In my former appllcation for patent Serial No. 7 6,810, filed February 5, 1916, I described such a stove in which the oven door was provided with a draft chamber communicating with the inside of the oven and with the top draft above the oven. The gas was introduced beneath a false bottom in the oven and circulated through the oven and out through the door. Such a door when cold is forced to take the first heated air and burnt gas both on the inside of the oven and in the interior of the door, and the condensed water will be considerable.

Of course any oven door has condensation water on it after the starting of combustion of gas, in a gas stove, and my invention is not limited in its application to the particular form of gas oven above referred to, although in such connection it has speclal value because of the fact that the door must take all of the heated air and gases out of the oven.

It is my object, therefore, to provide a drain chamber for waters of condensation for the inside surface of an oven door, and for the interior of such doors as have a fine chamber therein, and generally for all oven or stove walls.

These objects I accomplish by that certain construction and arrangement of parts to be hereinatfer more specifically pointed out and claimed, wherein a chamber is provided to take the waters that flow away, same being of a suflicient size to retain all such waters until they are evaporated by the heat in the oven.

Specification of Letters Patent.

Patented July 3, 1917.

Serial No. 108,091.

In the drawing,

Figure 1 is a vertical section taken ghrougli an oven door, having a flue cham- Fig. 2 is an elevation of such door, taken from the inside of the oven to which it is secured.

The stove body 1 is formed with an oven 2, in the base of which is mounted a burner 3. Over the burner and resting on the oven is a false bottom 41, which is to be removed when the stove is not to be used for gas.

The oven door has an outside wall 5 and an inside wall 6, which two walls form a flue chamber. The inside wall terminates above the base of the door so as to form a chamber for housing the burner, and the door and burner both swing on a pivot 7, all as described and duly claimed in said ap plication for patent above referred to.

In the chamber or inner wall of the door is formed a flue aperture 8 controlled by a damper 9, and at the top of the door and in communication with the chamber therein is a fine passage 10 to the oven space above the door.

At the base of the flue chamber in the door is mounted a plate 11 which is suitably affixed to the outer lining or wall of the door and depends slightly. The inner wall slants outwardly at 12 near the lower end, and is afiixed by a suitable water-tight joint 13 to the depending plate.

The plate extends beyond the inner wall and there is provided with an upwardly extending flange 14 which forms a trough on the inside wall of the door. Owing, however, to the outward slant of the wall, the flange does not protrude into the oven, but lies flush with the wall.

As so constructed, when the water of condensation flows down the door, that on the inside will be stopped by the depending plate and held confined until the heat of the stove is suflicient to evaporate it. The water on the inside wall of the door will run down into the trough or channel formed by the plate and the flange 14, which is to be of sufficient size to hold all of the condensation water that will flow under all but extraordinary conditions. The water thus held will. evaporate as soon as the stove is fully heated up.

In a stove arranged as the specific stove above described, this collection of water specially valuable, because ifallowed to run off of and out of the door, the water will fall around the burner which lies just inside the inner wall of the door, thereby subjecting it to rust, and the space around it to the collection of dirt and rubbish.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In combination with a stove oven for gaseous fuel, a door for said oven, said door being formed with a line chamber therein, a plate mounted at the base of said chamber, said plate extending beyond the inner wall of the chamber and flanged upwardly so as to catchall condensation waters 111 the door oron the inner wall .of theflehainber.

2. In a stove oven for gaseous fuel, an inclosing wall for said oven, said wall belng turned outwardly from its main surface ad- WILLIAM L. MERSFELDER.
